Antigen detection kit colloidal gold method generally refers to the new crown antigen detection kit colloidal gold method, the use of the method is the antigen test before the preparation, the collection of samples, to carry out antigen testing, the results of judgment. 1. Preparation before antigen self-testing: Before antigen testing, you need to wash your hands, understand the use of antigen self-testing reagents and precautions, and also check whether the antigen self-testing reagents are broken. In addition, colloidal gold test strips need to be placed at 14~30℃. 2. Sample collection: Before sample collection, the head should be tilted slightly, and then the nasal swab should be inserted into the nasal cavity at a depth of 1~1.5cm, and then attached to the nasal cavity and rotated for 4 times, and the collection time should be 15 seconds. In addition, the specimen from the other side of the nasal cavity should be collected in the same way. 3. For antigen detection: After the sample collection, the sample of the nasal swab needs to be placed in the sampling tube, at this time, the swab head needs to be rotated and mixed in the preservation solution for 30 seconds. Then squeeze the liquid from the swab head through the wall of the test tube, and discard the swab head afterward. Finally, the liquid in the sampling tube needs to be dripped into the air of the sample of the test card, and the result will be out in 15~20 minutes in general. 4. Judgment of results: If the test card C area, no red line appears, that is invalid results. If the red line appears in the C area of the test card, but no red line appears in the T area, it means that the test result is negative. Alternatively, a positive result is indicated by the presence of red lines in both the C and T zones of the test card. Jian use the antigen test kit colloidal gold method under the guidance of the instruction manual, and if the antigen test is positive, seek medical attention for nucleic acid testing.
